I'm in a bit of a pickle here. I have an Atom 330-based tiny computer which I use as my HTPC. It performed its job fine running Windows 7 and Boxee, and over the past few months, it ran Mac OS X Leopard with Plex. Now, however, I want to try Linux as an HTPC operating system, but I kind of ran into a roadblock there with Ubuntu 9.10 - so the question is: what is a good HTPC Linux distribution?
